napi 0.3.0

Export Dart functions as native WebAssembly ES modules with JavaScript interop and TypeScript declarations.

0.3.0

• Export flat Dart Lists and String-keyed Maps with scalar values, nullable containers/elements, and Future completion types.
• Generate exact Array, Record, and Promise declarations from resolved signatures.
• Validate dense own-data Arrays and ordinary object fields without invoking getters; preserve cross-realm values and special Map keys.
• Copy complete input containers before business code runs and independent results on completion; report conversion paths in errors.
• Measure collection conversion costs and emit collection helpers only where needed.
• Preserve original JavaScript errors when hostile stack accessors or prototype traps throw during diagnostic extraction.

0.2.0

• Export ordinary Dart Future<T> functions as native Wasm functions returning JavaScript Promise<T>.
• Generate precise Promise declarations for supported values, nullable results, and Future<void>.
• Reject input errors, synchronous throws, async failures, and unsafe results consistently; preserve non-null JavaScript exceptions and expose Dart stack traces. JS null/undefined failures follow SDK exception wrapping.
• Copy byte inputs before awaiting and byte results on completion.
• Safely format Dart exceptions and stack traces that throw during toString.
• Add reproducible build, package-size, cold-import, and conversion benchmarks.

0.1.0

• Export annotated Dart functions as real Wasm ESM named functions.
• Generate npm entries that point directly to Wasm, with automatic host interop.
• Emit .d.ts package declarations and relative .wasm TypeScript companions.
• Support booleans, safe integers, doubles, UTF-16 strings, copied bytes, and nullable values.
• Check argument types, preserve readable errors, and copy Buffer/cross-realm bytes.
• Validate signatures and protect output directories with staged replacement.
• Use Dart 3.13.5 experimental Wasm interop and Node's experimental Wasm ESM integration.
